I have had multiple blue screens over the past few months. My laptop is 1 year old. They mostly occur while I am playing games such as Garry's Mod or Battlefield Bad Company 2. I have had DRIVER_IRQL_NOT_LESS_OR_EQUAL, IRQL_NOT_LESS_OR_EQUAL, UNEXPECTED_KERNEL_MODE_TRAP, PAGE_FAULT_IN_NONPAGED_AREA and MEMORY_MANAGEMENT Blue screens. As you can see I have had lots of different types and it is very frustrating. The most recent one was the UNEXPECTED_KERNEL_MODE_TRAP blue screen. I really need help with this problem.

Let us start with the basics first. Since varying BSOD is generally a sign of failing memory modules, please run a stress test with free tool Memtest86+ . Please read instructions from the below tutorial for detailed info.

As the tutorial states, you should run at least seven passes for an accurate result. It may take several hours to complete so please be patient or run the test over night. You can stop the test immediately if there are errors detected.

You don't need to open the laptop to remove the RAM modules. Memory can be accessed by removing a small cover at the bottom. It's easier than you thought. Just watch the below video tutorial for detailed steps.

Once you identified the failing module, either keep it unplugged and run the system with the good 2GB module or buy a replacement kit like the one below.

Remove the RAM module from it's currently plugged socket and plug it in to the other empty socket. Now rerun Memtest86+ either until you got errors or it completes eight passes. If it shows errors, you should replace it with a compatible new module.
